Even if you've signed up for the National Do No Call Registry, a few spam text messages or phone calls might slip through the cracks. Reddit user jaxxon recommends creating a contact for each one so you can easily ignore them.

Depending on what type of phone you have, once you save the contact you can then edit it so the calls go directly to voicemail, the text messages are silent and don't send alerts, or you can block them entirely. The contact trick is especially useful when you're thrown on a text messaging "deals list" from retailers without your knowledge.
